PYB10-Q24-D5

The PYB10-Q24-D5 is a 10W isolated DC-DC converter from CUI Inc., part of the PYB10 series. It features a wide 4:1 input voltage range of 9 to 36 Vdc with a nominal 24 Vdc input, making it suitable for applications with varying input supplies. The converter delivers dual regulated outputs of +5 Vdc and -5 Vdc, each capable of supplying up to 1 A of current, for a total output power of 10 W.

Key electrical characteristics include a typical efficiency of 83%, a switching frequency of 350 kHz, and maximum ripple and noise of 80 mVp-p. The converter provides 1500 Vdc input-to-output isolation, ensuring safety and noise isolation in sensitive systems. Line regulation is ±0.2% typical (±0.5% max), and load regulation is ±0.5% typical (±1% max), with voltage accuracy of ±1% typical (±2% max).

The converter is housed in a 6-DIP through-hole package measuring 50.8 mm x 25.4 mm x 11.8 mm, with a six-sided metal shield for improved EMI performance. It includes remote on/off control (active high enable), overvoltage protection (OVP), and continuous short circuit protection (SCP). The operating temperature range is -40°C to 85°C, making it suitable for industrial and commercial environments.

This converter is designed for ITE (commercial) applications and is RoHS and REACH compliant. It is a reliable choice for distributed power architectures, battery-powered equipment, and board-level power conversion requiring dual ±5V rails.
